Some note for Roles & Task

for PM Role:

Ensure document enough for reference (specifications, database, business rule, code sample document – some thing like how to implement … in this project) (follow up work-flow, and ask what data, how, why, when, what, any differ from, how to handle if status/value = enums).
Avoid conflict between business rules/requirement.
Split tasks, set expected finish date, track progress (percent of finish, problem).
Assign task based on previous works & available time (tasks should related)
Ensure code consistency, follow patterns, convention, backward compatible (with Senior/TA to suggest & approve model, code review (1)).
Each code sample should be approved based on 2 options(better from 2 dev/senior).
Avoid multi-track of code (one issue but handle my more than one place).
Ensure process of task (review reference code if new task before implement, implement, video test).
Valuate performance base on the arguments in team (=> have to track it), and work result (deadline, idea, code quality, team co-working).
Ensure enough scenarios in check list form.

for Senior/TA Role:

How to handle common issues (log, display error, transaction) consistency
Functional programming => easy extend/modify in future.
Apply design pattern as possible, choose which model so that general enough, less & template work/care for devs, performance, flexibility (1), backward compatible.
Keep in my, this code/business rule can be change in future.
Flow best practice of framework.
Implement & document sample code (some thing like how to … in this project).
Ensure code consistency, follow patterns, convention (with Senior/TA to suggest & approve model, code review).

for Dev Role:

code follow samples (how to implement in this project document).
Keep in mind about the convention.
Functional programing & self-comment code.
Test carefully and record video.
Suggest better model, alarm conflict/duplicate between business rules, code model.
reported implemented cases/scenarios, in check list form.

some note for cross browser

1. float & display order.

2. double margin + float in ie6.

3. css selector base on attribute [name=value] on IE6.

4. max-height, max-width on ie6.

5. png transparent backgroud in IE6.

6. opacity issue (filter vs opacity vs -moz-opacity)

7. clear break & overflow: auto

8. body center-align: margin-left: auto; margin-right: auto;

9. table-less form: use div.form-row and clear: both, fix focusable div in ff2
